13C isotopic fractionation of HC3N in star forming regions
[Abstract]
I will talk about observations with the Nobeyama 45-m telescope during this observational season. We investigate 13C isotopic fractionation of HC3N and discuss its main formation mechanisms in L1527 and G28.28-0.36.

Chemical Composition in a Merging Galaxy NGC3256 ~ALMA new results~
[Abstract]
NGC3256 is late stage merging galaxy and SB/AGN activity is considered to strongly impact the chemical and physical properties of ISM. Chemical properties as traced in molecular gas composition contain significant information that will tell us the current state and duration of the SB/AGN activities, and how that is affected by the ongoing tidal interaction. The spectrum of our previous LMT line survey seems to be like SB galaxies not AGN-host galaxies, however it reflects mean value of double nuclei. High resolution and sensitivity imaging of numerous molecules with ALMA is strong tool to create accurate picture of NGC3256. We introduce the newest results of ALMA cycle3 observation.

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs)
[Abstract]
I will present recent updates of high-redshift (z>6) quasar search project using Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) survey, with which we have succeeded in identifying 9 z>6 quasars from the initial data release. Also, I will show the result of another faint quasar search at z~6 using deep Subaru/Suprime-Cam images.
